BOTZ vs. KOID vs. ROBO: Which Robotics ETF Fits Your Portfolio in 2026?

Three funds, three strategies. Here's what actually separates them — and which kind of investor each one suits.

PUBLISHED 2026-07-26 · UPDATED 2026-10-05 · ETF_01

BOTZ, KOID, and ROBO take three different approaches to robotics investing. BOTZ holds 81 industrial-robotics and AI stocks, with FANUC, Intuitive Surgical, NVIDIA, Keyence and ABB each near 8% of the fund. KOID, launched in June 2025, targets the humanoid-robotics ecosystem across 64 positions. ROBO spreads across 81 robotics and automation companies, with its top 10 making up only about 17%. As of early October 2026, ROBO is up 16.88% year-to-date, KOID is up 12.84% (as of September 30), and BOTZ shows a one-year NAV return of 0.06%.

Figures from Global X (BOTZ, Oct 2, 2026), KraneShares (KOID, Oct 2 and Sept 30, 2026) and ETF Database (ROBO, Oct 2, 2026). Different sources use different calculation dates, so treat the comparison as approximate.

Why the return gap?

The three funds are built differently. BOTZ puts about 8% each into five names (FANUC, Intuitive Surgical, NVIDIA, Keyence and ABB), roughly 40.6% combined, so its return depends heavily on a few large companies. ROBO's top 10 holdings are only about 17% of the fund, so no single stock moves it much. KOID's five largest positions are each around 2%, but many of them are semiconductor, test and sensor suppliers (Teradyne, Cognex, Renesas, Analog Devices) rather than robot makers, so the humanoid theme shows up as a supply-chain bet. Concentration is one reasonable explanation for the gap, not a proven cause, and past performance does not predict future results.

BOTZ vs ROBO

BOTZ is cheaper (0.68% vs 0.95%) and larger (about $3.16B vs $2.02B), but far more concentrated. ROBO has more even weights, carries a higher fee, and has returned more over the past year (22.13% vs BOTZ's 0.06% NAV return). Pick BOTZ if you want large-cap industrial and AI leaders at the lowest cost; pick ROBO if you want broader diversification and accept the higher fee.

KOID vs BOTZ

KOID is a much newer and smaller fund (launched June 2025, about $334.8M) built around the humanoid-robotics supply chain, while BOTZ has held a roughly 10-year record in industrial robotics and AI. KOID's net fee is 0.69%, almost identical to BOTZ's 0.68%. KOID's holdings are far more evenly weighted, and it has a short track record, so long-term comparisons are not possible yet.

KOID vs ROBO

Both are spread across dozens of holdings. KOID focuses on humanoid-robot components and enablers; ROBO covers the full robotics and automation value chain, from surgical robots to industrial automation, and has an older history (since 2013). KOID costs less after its fee waiver (0.69% net vs 0.95%).

Which one fits which investor?

Want the lowest cost and can tolerate concentration risk: BOTZ at 0.68%, with about 40% of the fund in five stocks.

Want exposure to the humanoid-robotics theme and accept a short track record: KOID, with a small fund size and limited history.

Want the broadest diversification: ROBO, at the highest fee of the three (0.95%).

The bottom line

Each fund is a bet on how fast and how broadly robotics grows, and how concentrated you want that bet to be. Cost, concentration and how closely the fund tracks the humanoid theme are the three things that separate them. Check each fund's fact sheet for current figures before making any decision.

Frequently asked questions

Is BOTZ or ROBO the better robotics ETF? Neither is better for everyone. BOTZ is cheaper (0.68% vs 0.95%) and more concentrated, with five holdings near 40% of assets. ROBO is more diversified (top 10 about 17%) and has returned more over the past year according to ETF Database and Global X.
